31 Claims.

This invention relates to improvements in solefitting machines and isillustrated herein as embodied in a channeling machine which is adaptedsharply pointed-toe style is considerably more diflicult than is thesame operation on a broadtoe style because the turning radius is smallerin the pointed-toe sole with the result that there is less room in whichto make the turn.

It is an object of this invention to provide improvements insole-fitting machines which will make it easier for operators to turn orswing soles about sharp corners. To this end, the illustratedmachinawhich is equipped with a pair of knives arranged to operate onthe marginal portion of a sole, is provided with means which can beadjusted during the operation of the machine to shorten the stroke ofthe knives when the operation approaches a sharp corner, and, inaddition, the machine is provided with further means which is arrangedto slow down the speed of the knives when their stroke is shortened.This construction makes it easier to turn the sole and also retards thespeed of the feed which is desirable when operating around corners. Thecontrols for the above-mentioned means are both connected to a treadleso that when the operation approaches a corner, the operator can shortenthe stroke of the knives, reduce the rapidity of their movement, andretard the speed of the feed by operating the treadle with his foot, andat the same time he can use both hands to swing the sole about the pointof operation.

Further to facilitate turning of the sole, and in accordance withanother feature of this invention, means are provided for disengagingthe feed device from the sole member during a substantial part of eachoperating cycle. As illustrated, this means comprises a cam which movesthe feed device heightwise from the sole member at the end of eachcutting stroke and holds it away from the work fora substantial periodduring each operating cycle so-as to give the operator ample opportunityto adjust the position of the sole between the successive cutting"strokes.

'Hereto fore, when it was desired to channel an insole having anextension-such, for example, as the wing "or tab portion of anorthopedic insole -andto chamfer or bevel the-edge of the sole at therower 'or'grain side, it was necessary to perform two separate machineoperations, i. e.,

channeling and beveling. This was due to the fact that beveling knivesin machines heretofore available could not be moved out of the path ofthe relatively wide sole extension on this't'ype of in'sole during theoperation of the machine "and hence would gouge the under or grainsurface-of the "extension if a channeling operation were carried out inthe portion of the sole contiguous to the extension.

With this in view, it is another object of the invention-to provide animprovedsole-fitting'machine which is capable of simultaneouslychanneling and beveling themargin'al portion of an orthopedic insole andthus accomplishingin one machine operation results whichyhave heretoforerequired two separate operations. To this 'the provision of mountingmeans for the chamfering knife which is so arranged that the chamferingknife can readily be moved below the surface of the "work table duringthe operation of the machine and thus permit the sole extension to passover the chamfering knife without being cut thereby and the channelingoperation to progress through the portion of the sole contiguous to theextension. In accordance with another aspect of this feature of theinvention, means are provided for interconnecting'the-edge gage and thechamfe'ring knife so that the edge gage can be moved out of the path ofthe 'sole extension at the same time the chamfering'knife is moved belowthe surface of the work table. As illustrated, the interconnectededge'gage and chamfering knife are mounted 'on the worktable carrierwhich is arranged to adjust them transversely to the line of feedthrough a normal range of adjustment and, when an extension of the soleis encountered, 'to 'move'them to a predetermined position 'Where anabutment acting on the interconnecting means causes the edge gage andthe charnfering knife "to move heightwise of the surface of the worktable to a position where they are out of the path of the soleextension. It has been found that in sole-fitting machines wh'ifetheknives "and the feed devices move in ream paths, the feed of the "workWith this in mind, it is another object of the.

invention to provide further improvements in sole-fitting machines,which will overcome rotatable work table l2 which is mounted on anadjustable carrier l3. Adjacent to one side of the work table is achamfering knife 14 (Fig. 3) which is also supported on the carrier,while above the work table is an inner tool carrier I6, and an outertool carrier !8. The elements just mentioned correspond respectively tothose indicated by the numerals 14,40, 420, 62 and 64 in theabove-mentioned patent to Bertrand.

The inner tool carrier'lfi (Fig. 2) is mounted for straight linemovement by means of a pair of plates 20, 22 which are fastened to thetool cartwitching of the sole as it is fed past the chamfering' knifeand thereby improve the appearance of the beveling cut made by thatknife. This object is attained by mounting one of the tool-supportingmembers for straight-line movement, and the other tool-supporting memberfor In accordance with a preradial movement. I ferredarrangement, theouter or edge knife'and the inner or channeling knife are mounted on thestraight-line tool-supporting member, and a feed device is mounted onthe radially movable member, Movementof the channel knifein a straightline practically eliminates the throw of the work against theedge gage,while the solegripping action of both of the knives largely prevents thefeeding forces from moving the sole away from the edge gage. g V

Invention is also to be recognized in the driving mechanism foroppositely moving the radial and the straight-linetool-supportingmembers, and in the simple. and efficient control system for raising andlowering the work-feed device in timedrelation to the movement of thetool carriers. u

With the above and other objects in view, the invention will now bedescribed with reference to the accompanying drawings, and will bepointed out in the appended claims.

The'machine shown in the drawings is of the type illustrated in LettersPatent of the United Si ates'No. 2,015,064, granted September 24,1935upon application of F. E. Bertrand,"and comprises a .headlfl in whichismounted a freely rier by screws 24 and engage respectively theopposite undercut sides of a dovetailed guideway 26 formed on the insideof the end wall 21 of the head I0. A tool slide 28 is mounted forvertical movementin a slideway 36 within the tool carrier it. The slide28 is adapted to yield upwardly against the action of a coil spring 32which is housed within a bore in the upper part of the slide, the upperend of the spring bearing against afollower .34 which is engaged byanadjustable screw 35 threaded in a collar 38 clamped-to a pin 40 which,in turn, is fastened to the upper plate .26. Downward movement oftheknife slide 28 under the influence of the spring 32 is limited by acrossbar l2 which corresponds to the crossbar 23$ inthe machinedisclosed inthe above-mentioned Bertrand patent. a

The outer tool carrier !8 (Fig. 2) is located opposite to the straightline carrier l6 and is provided with laterally extending heightwisespaced arms 44, 45 which extend over the top and bottom surfaces of ashoulder Q8 formed on the head it. The carrier I8 is pivoted to theshoulder 18 by a hollow sleeve 50 which extends through alined openingsin the arm 44, the shoulder 48 and the arm 46, the sleeve being attachedto the arms by means of pins 52. The axis of the pivot sleeve isvertical and normal to the plane of a sole on the. sole support I2, andoscillatory movement about this axis will not therefore includeup-and-down components relatively to the sole. A second slide 54consisting of a spindle 56 and a sleeve 58 is mounted for verticalmovement in. a slideway 60 within the carrier. l8. A feed foot 82' iscarried by the lower end of the spindle 56.

The sleeve 58 is formed witha counterbored recess for receiving a coilspring 62 which en.-

'circles the spindle'56, the lower'endof the spring to the sleeve 58 andmaintain the spindle in a vertical position determined by;the engagementof a crosspin S6 in the spindle with the lower end of a vertical groove68, in the sleeve .58. The spring will be compressed by continueddownward movement of the'sleeve after the tool carried by the spindle 56has engaged the'work on the table 12, thus adapting the tool carrier.spindleto a-ccommodate soles ofdifferent thicknesses.

The sleeve 58is provided. with an ear lilwhich is connected to aswinging lever 12 by a link 14, the lever being mounted on a transversecrossshaft 16 which is carried by spaced uprights 18, 30 (Fig. 1)". Asthe tool carrier l8 moves the sleeve 58 laterally with res-pect tov thepath of movement of the lever 72, V ballandsocket joints are used toform the connections between the ear 1a, thelink I l and the lever 12,these joints preferably being of the'type shown in the United l I vStates Letters Patent No. 2,173,155, granted September 19, 1939 upon anapplication filed in the name of F. E. Bertrand.

In the illustrated form of my invention, the channeling knife I50 (Fig.4), the edge knife I52, and the presser gage I54 are all fastened to theknife slide 28 on the tool carrier I6. The means for fastening thechanneling knife to the slide consists of a screw I56 which passesthrough an opening I58 in va knife block I60 and then into threadedengagement with the channeling knife. The block I60 is securedto aknife-block holder I62 by a screw I64 which passes through a hori--zontal elongated opening I66 in the block holder and then into threadedengagement with a tapped hole I68 in the knife-block I69; the elongatedopening I66 permitting lateral adjustment of the channeling knife. Theknife-block holder I62 is clamped to the slide 28 by a quicklyreleasable connection consisting .of .a slotted cap plate I70 which fitsaround the head of a screw I72 that passes through a second elongatedopening I74 in the block holder I62 and then into threaded engagementwith an opening I76 in the tool carrier. vertical direction, making itpossible to adjust the channel knife in a heightwise direction. When theknife-block holder I62 has been moved to a desired heightwise positionand clamped against the tool slide, the screw I72 is held againstrotation by a clamp screw H8. To release the knife-block holder I62, thecap plate I70 is rotated in a counterclockwise direction a shortdistance to loosen the screw I72 and the cap plate is slid out fromunder the head of the screw, thus loosening the screw so that it can bebacked off by hand if desired.

The edge knife I52 is mounted on a knife block I80 which is fastened toone end of a bracket I82 by a screw I84 which extends through anelongated vertical opening I85 in the block I80. The bracket I82 extendslaterally from the slide 28, and is connected thereto by a screw I86.The screw I84 is provided with a slotted cap plat I88 which functions inthe same manner as the cap plate I78 and, in addition, the screw islocked in its tightened position by a clamping screw I87. The pressergage I54 is fastened to a notched portion of the lower end of the toolslide 28 by a screw I92 (Figs. 3 and 4). The presser gage extendsparallel to the bracket I82 and is provided with a pair of spaceddownwardly extending presser feet I94, I96 which are located a slightdistance in advance of the channeling knife I50 and the edge knife I52.

The tool carriers I6, I8 are oppositely moved back and forth by a lever86 (Figs. 1 and having 21. depending spindle 88 which is pivoted in abearing 89 on the top of the head I0. The lever 86 is connected to acrank arm 90 on the outer tool carrier I8 by a link 92, and to the hingejoint 96 of a toggle which operates the slide I6 by a second link 94.The toggle consists of an arm 98 pivoted on a post 99 extending upwardlyfrom the head I0, and a link I00 connected at one end to the pin 40 onthe upper plate 20, the arm 98, link :00 and link 94 being connectedtogether at the hinge joint 96. Thus, when the lever 86 is moved in acounterclockwise direction, as viewed in Fig. 1, the crank arm 90 isrotated in a counterclockwise direction, causing the tool carrier I8 tomove rearwardly, and at the same time the arm 98 is also moved in acounterclockwise direction moving the hinge joint 86 for- Tne elongatedopening I74 extends in a 1 'wardly and causing the tool carriage I6 tomove forwardly. I

The link 82 is connected to the lever 86 by a slide I02 (Fig. 1) whichis mounted in a'groove I04 formed in the top of the lever, and theextent of movement of the tool carriers is varied by adjusting the slidein the groove relatively to the axis of oscillation ofthe lever. Theadjustment of the slide I02 is effected by the operation of a lever I06which is connected-to the link 92 by an adjustable link I08, the leverbeing operated by a rockshaft IIO which extends rearwardly beyond thehead I0 to a point where it is connected with a treadle (not shown) bymeans of a. rod II 2 (Fig. 3). The rockshaft .0, rod H2, and the treadle(not shown) correspond respectively tothe members 648, 656 and 658 inthe patent to Bertrand No. 2,015,064.

The lever 86 is oscillated back and forth by a three-motion cam II4(Fig. 5) which is surrounded by a cam-follower housingIIB that is movedback and forth by the cam, the housing II6 being connected to the lever86 by a pin II8 (Figs. 1 and 5) which is fastened to an upstanding armI20 on the rear end of the lever 86. The cam H4 is mounted on the upperend of a vertical drive shaft I22 which corresponds to the drive shaft'70 in the before-mentioned Bertrand Patent No. 2,015,064.

The cam H4 (Fig. 5) consists of a segment I24 of uniform radius, asegment I26 of decreasing radius, a third segment I28 of uniform radius,this radius being less than that of the segment I24, and a fourthsegment I30 of increasing radius. When the cam is rotated in a clockwisedirection from the position shown in Fig. 5, the segment I26 causes thelever 86 to move in a counterclockwise direction and the knives I50, I52on the one hand and the feed foot 82 on the. other hand to move towardeach other on a cutting stroke. At the end of this movement, the segmentI24 causes a dwell or suspension in the movements of the tool carriers,after which the segment I30 causes the tool carriers to reverse theirmotion and move the knives and the feed foot back to their startingpositions; and, when they. reach those positions, the segment I28 willcause a second dwell. A the cam I I4 rotates, it acts on wear platesI32, I34, which are mounted in 'the cam follower H6, and is lubricatedby wicks I36 that are mounted in oil pockets formed in the cam follower.

The arrangement described above substantially eliminates thebefore-mentioned twitching which heretofore accompanied the work feedand makes it possible for the chamfering knife to form a smooth, beveledsurface. This is due to the fact that movement of the channeling knifein a straight line practically eliminates the throw of. the work againstthe edge gage, while the gripping action of the knives I50, I52 and thepresser feet I94, I96 on the work largely prevents the action of thefeed foot 82 from moving the .sole edge away from the edge gage.

The heightwise movement of the feed foot 82 is controlled by a pin I88which extends upwardly from the cam H4 .and is located eccentrically tothe underlying drive shaft I22 (Fig. 5), the eccentric pin beingconnected by a .link I40 (Fig. 1) vto the swinging lever 72 which raisesand lowers the feed foot. The eccentric pin is so located with respectto the control surfaces of the cam II4 that the pin lifts the feed footfromthework during the dwell which follows thefee'd stroke and holds thefeed foot .away

from the work throughout the return movement of the tool carriers andWell into the dwell which follows this return movement. Thus it' will beseen that during each operating cycle of the machine which is caused bythe rotation of the drive shaft I22, the feed foot is disengaged fromthe work for approximately three-fourths of the operating cycle, givingthe operator ample time to adjust the position of the work between eachcutting stroke.

'When the operation. approaches a sharp corner, the operator customarilyshifts the block I02 closer to the fulcrum of the lever 84, therebyreducing the amplitude of the oscillations imparted to. the toolcarriers I6 and I8, shortening the stroke of the knives, and reducingsomewhat the speed of the feed. The speed of the feed in the illustratedmachine is further reduced at this time by reducing the frequency of theoscillations of the tool carriers, this result being obtained bymakingthe vertical drive shaft I22 in two sections (Fig. 3) and connectingthose sections by a friction-type slip clutch I42. The lower element ofthe clutch I42 is provided with a sleeve I43 which is slidably mountedon the lower section of the drive shaft I22 and has a peripheral groovein which are seated shifting pins I44.

The controls for the block I02 and the clutch I42 are interconnected bymeans which will now be described, so that the speed of the uppersection of the shaft I22, to which the cam H4 is connected, willprogressively be reduced as the block is moved closer to the fulcrum ofthe lever 86. To this end the shifting pins I44 are connected to aforked lever I45 (Figs. 1 and 3) which is in turn connected at I41 tothe treadle operated rod II2 which controls the shaft H and through itthe block I02. Thus, by depressing the treadle (not shown), the elementsof the slip clutch I42 will be moved apart as the stroke of the toolcarrier is shortened, thereby causing a slow-down in the frequency oftheir back and forth movements.

The chamfering knife I4 is mounted on a knife carrier 200 (Figs. 3 and6) which is pivoted on a lug 202 that projects upwardly from a flatlever 2 34, the lug being located beneath the edge of the work table I2.The lever 204 rests 'on the top of the work table carrier l3 and isswingably connected .at its left end (Fig. 3) to a stud 206 whichprojects upwardly from the carrier I3. The opposite end of the lever 204is attached to the lower portion of a post 208 that extends through aslot 2 (Fig. '7) in the forward end of an edge gauge supporting member2I0 and has its upper portion connected, to an auxiliary work-supportingtable 209 so that the auxiliary table moves with the lever. The

lever 204 is connected to the member 2I0 by a pin 20'! which extendsthrough alined openings inthe lever and the member. The edge gagesupporting member 2I0 is rectangular in shape and has an arm 2I2 whichextends upwardly fromits rear, or the right portion of the memberasviewed in Fig. 6, the upper end of the arm being provided with a lateralextending pivot pin 2I'4 upon which an edge gage 2l6 is mounted.

The edge gage 2I6 and the chamfering knife I4 are oscillated back andforth by a rocker member -2I8 which is provided with a pair of spacedarms 220 (Fig. '7) which slidably engage the opposite sides of the edgegage supporting member 2I0, thereby causing the member 2I0 to oscillatewith the rocker member 2! while permitting relative sliding horizontalmovement be tween the members as required to permit inward and outwardadjustment of the work table carrier I3 and the edge gagev 2I6. Therocker member 2I8 is pivoted on the head I0 by a post 222 (Fig. 2) whichis fastened at, its lower end to the rocker member and extends upwardlyinto the opening in the sleeve 50 which also forms the pivot for thetool carrier I8. Movement of the tool carrier is transmitted to therocker member 2I8 by means of a flat plate 224 which projects downwardlyfrom the lower arm 46 on the tool carrier I8 into a slot 226 in theupper part of the rocker member. With the arrangement just described,the oscillating movements.

of the tool carrier I8 will be transmitted by the plate 224 to therocker member 2I8 and to the member 2I0 which moves in unison with therocker member. The member 2I0, in turn, transmits the oscillatingmovement through the pin 201 to the flat lever204 which is caused toswing back and forth about the stud 206. As chips are cut from a soleedge by the chamfering knife I4 they are carried away from the worktable by a chute 221 (Figs. 1 and 6) which is attached to the chamferknife carrier 200. From the chute 221 the chips pass through a secondchute 228 fastened to the work table carrier I3 by bolts 229 (Fig. 1).

The chamfering knife and the edge gage are adjusted back and forthrelatively to the channeling and edge knives I50, I52 by thebackand-forth movement of the work-table carrier I3 which is controlledin the usual manner by V a hand lever 225 (Fig. 7) which corresponds tothe hand lever 508'in the Bertrand Patent No. 2,015,064.

The'chamfering knife I4 and the edge gage 2I6 are arranged forheightvvise movement relative to the surface of the work table I2 sothat they can be moved out of the path of an extension on an orthopedicinsole. To this end, the edge gage 2I6 is provided with a downwardlyextending arm 230 which is connected to an arm 232 extending downwardlyfrom the chamfer knife carrier 200 by a link 234. The chamfering knifeand the edge gage are maintained in their normal operative position bymeans of a coil spring 236 which is connected at one end to the lowerend of the chamfering-knife arm 232 and at its other end to a pin 238which projects out from the mid-portion of the edge-gage arm 230.

The edge gage and the chamfering knife will remain in their normaloperative position shown in Fig. 6 while the work-table carrier I3 isadjusted back and forth to produce the usual variations in the Width ofthe feather about the periphery of an insole. When, however, an insoleextension is encountered, the work table carrier is moved to the right,as viewed in Figs.

3 and 6, anadditional distance, causing an abutment 240 on the edge-gagearm 230 to strike the end of an abutmet screw 242 mounted on the rockermember 2B8. This causes the edge gage arm 230 to rotate in a clockwisedirection, lifting the edge gage 2| 8 above the surface of the work, andat the same time, the displacement of the arm 230 moves the link 234 tothe left, as viewed in Figs. 3 and 6, thereby causing the chamfer knifearm 232 also to rotate in a clockwise direction and move the chamferingknife I4 below the surface of the work support, as shown in Fig. 3.

Clockwise rotation of the chamfering-knife arm 232 "and the edge-gagearm 230 causes'an appreciable stretch in the spring 236 so that.

when the work-table carrier I3 isagain. moved to the. left. sufficientlyto carry the abutment 24B. away from the screw 242, the. action of thespring on the'end of the chamfer-knife arm willcause that arm to move ina counterclockwise direction until it returns the chamfering knife tothe position shown in Fig. 6. This movement ofthe arm 232-wi1l cause acorresponding displacement of the link 234 which will move-the edgegagedown to its. operative position. The return movement of the chamferingknife and the edge gage will be stopped when the edge gage strikes theauxiliary work. table 209. It will be noticed that'the line of action.of the spring 236-passes closer to the pivot 214 of the edge-gage arm230 than. it does to the pivot 263 of the chamfering-knife arm 232 sothat. the action: of the spring will cause the movement oftherchamfering knife and the edge. gage to their operative positions intheimanner just described.

The, work table I2 is raised and lowered by a mechanism similar to thatdisclosed in the Bertrant Patent No- 2,015,064, and in order to makesure that the rocker member 216 follows the downward movement of thework-table carrier,,thepost 222 (Fig. 2) which is fastened to therockermember 213, is urged downwardly by a: coil" spring 244: which is housedwithin the sleeve. 56. The lower. end of the spring abuts the; top ofthe member 222- while the upper end of" the spring bears against afollower 246- which is engaged by an adjustable screw 248 threaded in anoverhanging; member 259; fastened to the toolcarrier I8;

The operation of the machinewillnow be described. After the channelingknife and the edge knife. are mounted on the knife carrier (Fig. 4), themachine is started and a sole is introduced into the machine in theusual; manner. As: the operation approaches a sharp corner, the operatordepresses the treadle. (not shown) moving the link H2 (Fig. 3)downwardly. This movement of the link causes the shaft M to rotate in aclockwise direction, as viewed in,

Fig. 1, moving the lever N16 with it. The movement of the lever- H36causes a corresponding movement of: the links. I68 and 92, which causesthe block I62 to move in the slot lM'toward the fulcrum point of thelever 86 thereby reducing the amplitude of the oscillationsimparted' tothe tool carriers 16- and I8. At the same-time, the downward movement ofthe link H2 causes the clutch; arm 165' (Fig; 3,) to move downwardly andseparate the clutch elements, allowing them toslip relatively to eachother and causing the machine to. slow down. After the operationprogresses around the corner, the operator releases the'treadle andthemachine resumes its normal operation.

As the operation'progresses around the periphcry of the sole. theoperator moves the handle 2255 back and forth to vary the width ofthefeather. in a desired manner. If the sole being operated; upon isoftheorthopedic type provided with anextension, the operator moves the handle22-5- to a predetermined position when the point of operation reachesthe extension. This moves the work-table carrier 13 an additionaldistance to the right, as viewed in Fig. 3, causing the abutment screw242. to strike the abutment' 2% and: move the edge-gage arm 230 in aclockwise direction. Movement of' the arm in this direction: lifts.theedge gage- 216 above: the insoleextension and also displaces the link234- to theleft, causing. the chamfering-knife carrier to move in aclockwise direction so asto; lower the chamfering knife l4 below thesurface of the Work table. When the point of operation passes beyond theextension, the handle 225 is moved back to one of its featherdetermining positions thereby causing the work-table carrier I3. to moveto the left and the edge-gage arm 230. to move away from the abutmentscrew 242. When the arm 23!). moves away from this screw, the spring 236moves the'edge gage 216 and the chamfering knife l4' back to theirnormal operating positions, shown in Fig. 6.
